We study continuous-time optimal consumption and investment with Epstein-Zin recursive preferences in incomplete markets. We develop a novel approach that rigorously constructs the solution of the associated Hamilton-Jacobi-Bellman equation by a fixed point argument and makes it possible to...

When investors disagree, speculation between them alters equilibrium prices in financial markets. Because managers maximize firm value given financial market prices, disagreement alters firms' value-maximizing investment policies. Disagreement therefore impacts aggregate investment, consumption,...

In this paper I propose a general-equilibrium model with proportional adjustment costs and industry-specific capital to study the firm migration phenomenon across market-to-book ratio. In my model, investors' desire to diversify their portfolios and investment frictions generate a mean-reverting...

This study constructs a model of a relationship-specific investment in a dynamic framework. Although such investment decreases operating costs and increases the current joint profits of firms in vertical relationships, its specificity reduces the ex-post flexibility to change a trading partner...

Using the word capital to represent two different concepts is not such a problem when government is responsible for only a small fraction of national investment and is reasonably effective (as in the United States). But when government is a major investor and is ineffective, the gap between...

Instability and uncertainty are important factors in Africa's poor investment record over the past two decades. A recent (but rapidly growing) literature has focused on how uncertainty and instability affect the adoption of fixed investment projects. That literature shows that if fixed...

In his q theory of investment, in his analysis of money demand and portfolio choice, and in his analysis of macroeconomic instability, James Tobin focused on expectations of returns on assets and on expectations of inflation. His research was informed by his close study of John Maynard...
